in place of regular crisco shortening can i use crisco butter shortening

They are both poisonous, chemical man made fats so I don't see a problem

Hi, again, sally. I just did a quick search (Google, of course), and found this FAQ page from the company that makes Crisco, directly on point:
http://www.crisco.com/about_crisco/faqs.aspx
They say, sure, go ahead! ;o)

What are you baking?

(Incidentally, Shirley Corriher really likes that product - or at least she mentioned in one of her books that she uses it a lot.) ;o)
